HOG-I-IOIST.

Specification of Letters Patent.

Patented July 4:, 1911.

To all whom it may concern:

Be it known that I, GUsrAv SCHMIDT, a citizen of the United States, andresiding at Cincinnati, Hamilton county, State of Ohio, have inventedcertain new and useful Improvements in Hog-Hoists; and I do declare thefollowing to be a clear, full, and exact description of the invention,attention being called to the accompanying drawing, with the referencecharacters marked thereon, which form also apart of this specification.

This invention concerns so-called hoghoists which are devices whereby inslaughter-houses live hogs are handled for the purpose of placing themin proper position for killing and for subsequent bleeding.

The invention relates to new and useful improvements whereby theconstruction of such devices as well as their manipulation and manner oftheir use become greatly sim- In the following specification andparticularly pointed out in the claims at the end thereof, will'be founda full description of my invention, together with its manner of use,parts and construction, which latter is also illustrated in theaccompanying drawing, in which z- Figure 1, is a side-elevation of thehoist. Fig.2, is a front-view of it with parts broken out and shows itin operation. Fig. 3,,is part of an elevation of the side opposite tothe side shown in Fig. 1, it being the right side of the apparatus wit-hreference to Fig. 2. Fig. 4:, is a sectional detail-view taken on line44 of Fig. 2. Fig. 5, is a detail View of a portion of thecarrier-chain.

The hogs to be killed are taken to the hoistone by one by means of ashacklechain 10, one end of which is attached to one of their legs. Theouter end of this chain is provided with a hook 11, whereby temporaryconnection is made to the hoist, after which this latter lifts the hogand delivers it onto the so-called bleeding-rail.

In most of the present forms of hoists, hook 11, is attached to anintermediate pendent member, or chain which forms a part of theelevating-means of the hoist. In my present form I do away with such anintermediate member and hang hook 11, directly onto the carrier-chain12, which latter for such. purpose is provided with a hook 13,

thereby providing for an which is rigidly connected to or forms a partof one of the links of this chain. A number of these hooks 13, may beprovided, which number depends upon the length of the chain. This chainis an endless one, sup- 1ported in a suit-able manner by guide-puleys.

In the simplest form, two pulleys are sufficient, a lower one and anupper one, ascending and for a descending chain-branch. A moreconvenient arrangement, permitting also a compact construction, is shownin Fig. 2, where two lower guide-pulleys 14c and 15, and an upper one16, are provided, around which the carrierchain passes, and by whicharrangement this latter presents always a horizontal branch A, anascending branch B, and a descending branch O. In either form ofarrangement, the ascending branch hoists the animal and delivers itdirectly onto the bleeding-rail 17, as shown in Fig. 2, the transitiontaking place by hook 11, which at the proper time leaves hook 13, on thechain and slides onto the rail. A suitable frame-work is provided tosupport the guide-pulleys and to suit their particular arrangement.W'hen three are used as shown, a sill 18, is provided and two inclinedmembers 19 and 21, connected at their upper ends by a horizontal member22, and by an intermediate member 23. This frame is duplicated as shownin Fig. l, to provide for support of the boxes which carry the shaftsupon which the pulleys are mounted. Power to move the chain is bypreference applied to the upper guide-pulley 16, a belt-pulley 24, beingmounted on its shaft 25. This shaft may be driven by directly appliedpower or by an intermediate pulley 26, on a shaft 27, the bearings ofwhich are supported on intermediate framemembers 23. Shaft 27, is drivenin any suitable way, a pulley 28, being shown on it. Suitable means tokeep the chain at proper tension are also provided which may be appliedat any part of it, except its ascending branch.

A tightening pulley 29, is shown in Fig.-

2, mounted on intermediate frame-member 23. The boxes which support theshaft of one of the guide-pulleys may also be used for the purpose bybeing arranged to be shiftable upon the frame-member upon which they aresupported. If this method is used the boxes of pulley 14, would'bepreferably so used.

A preferable way to provide hooks 13, is by inserting special links 31,one of which is enlarged edgewise and shaped accordingly to form theupwardly projecting hooks. See Figs. 4, 5, and 2, (descendingchainbranch). These special links, by means of pins 32, are connected tothe adjoining regular chain-links. Any tendency of the ascendingchain-branch to tilt while loaded is counteracted by providing twoguides 33 and 34, one above and one below the chain. This latter, whiletraveling from the lower guide-pulley 15, to the upper guide-pulley 16,passes flat-wise through the space between these guides. To reduce thefriction, rollers 35, are provided upon which the chain travels whilepassing through these guides. Pins 32, may be used to support theserollers. Of the guides the upper one 33, is carried on a flange 36,attached to frame-member 19. The lower guide 34, is supported bybrackets 37, attached to the front-side of said frame-member as bestshown in Fig. 4. Hooks 13, travel outside of these guides. See Fig. 4.

The bleeding-rail 17, is supported in any suitable manner as forinstance by brackets 38, and near its receiving end it may also beattached to the general frame of the hoist as shown at 39. Thisreceiving portion forms by preference and for convenience inconstruction, a separate piece 41, which is shaped to extendsufliciently into the path of hooks 11, while moved by hooks 13, of thetraveling-chain, so as to meet them about at the highest part of theirtravel. The shape of this piece is further such, that from this point itdeclines until it meets rail 17 proper, the object of this decline beingto cause hooks 11, to promptly leave hooks 13, as soon as these latterhave moved over the turn at the highest part of their travel. This hooks11 do, by sliding here ahead of hooks 13, thereby clearing these latterat once, receiving also an impetus at the start of their movement whichsends them quickly ahead onto the bleeding-rail. (See Fig. 2, upperportion). A manner of construction which adds considerable strength tothe structure is by continuing the bleeding-rail all the way downalongside and in front of and slightly spaced from the edge of theascending chain-branch B, thereby forming a track 42, on which theshackle-hooks slide while being pushed up by hooks 13, on the chain.These latter hooks travel here in the space between this track-rail 42,and guide 33, and project beyond both as best shown in Figs. 1, 2, and4. Brackets 37, which support guide 34, may also serve to support thistrack-rail. j

A valuable feature connected with the hoist is the uninterruptedcontinuity of the track with the bleeding-rail, whereby the loadedshackle-hooks pass smoothly from one onto the other and are depositedupon the bleeding-rail without a jerk or jar which leads frequently toaccidents and causes damages of various kinds, bruises, dislocation ofjoints and breaking of bones which impair the appearance of the meat. Amiss of the bleeding-rail by the shackle is of course an obviousimpossibility. Track 42, may also be continued aroundbelow and in frontof the horizontal chain-branch A, as shown at 43, where, while it has noparticular operative function, this continuous part serves inconjunction with track 42, and a timber 44, to support a wall 45, whichis provided to close the front of the apparatus.

WVhere the supporting means for the carrier-chain are arranged toproduce such a horizontal chain-branch A, as shown, I provide meanswhich permit engagement of hooks 11, with hooks 13 on the chain whilethis latter travels through this stretch. These means consist of amember which I call a hooking-on rail, shown at 46, .It is providedbelow this horizontal chainbranch, being attached in a suitable mannerto the general frame or, as shown, to legs 47, which support sills 18,ofthe hoist. It relieves the operator from watching closely the hookstraveling with the passing chain for the purpose of enabling him to hangone of the shackle-hooks 11, onto one of these hooks. Instead he merelyhangs the shacklehook onto this rail 46, which is so located as to causethis hook to hang into the path of hooks 13, so that it is readilytakenv up by the first one of them which passes. See Figs. 1, 2, and 3,lower part. This rail is continued around the lower end of the.ascending chain-branch and follows the same sufliciently until hooks 11,are fully engaged by hooks 13, so that these latter may carry themforward unaided.

The particular shape of the projections on the chain and thecomplementary shape of the attaching-member of the shackling-deviceswhich is received by it, are to be considered merely as approximatetypes and may be varied to suit circumstances- The shape of theattaching-member should always be such that it permits of attachment tothe carrier-chain and also meets the receiving-end of the bleeding-rail.I consider therefore any variation of the parts and structures shown,whereby a shackling device by direct attachment to a hoisting chain, isdelivered to a bleeding-rail, without the intervention of anyintermediate means, as the equivalent to my invention.

Having described my invention, I claim as new:

1. In a hog-hoist, the combination of an endless carrier-chain supportedin a; manner to present a horizontal, as well as an ascending branch andprovided with rigidly attached hooks which permit temporary connectionof the attaching hook of shackling-devices, ableeding-rail at the upperend of the ascending branch, a hooking-on rail parallel to and below thehorizontal chainbranch and arranged to permit the hooks of theshackling-devices to be hung onto the same in which position they dependinto the path of the hooks moving with the carrier chain and means tomove this latter continuously in one direction only whereby the hookshanging on the rail are taken up by the hooks on the chain and therebyelevated to the bleeding-rail and deposited therein.

2. A hog-hoist comprising an endless carrier-chain, supporting andguiding means which provide an ascending and a descending direction ofmovement for said chain, carrier-hooks provided on said chain from whichthey project upwardly at an inclination in the direction of movement ofsaid chain while ascending and downwardly while descending, ableeding-rail extending laterally from said chain-supporting and guidingmeans and in line therewith at approximately the highest point to whichthe hooks on the chain ascend and a shacklingdevice comprising acarcass-suspension hook adapted to be engaged by and supported upon saidcarrier-hooks and to be elevated by them to said bleeding rail, saidrail be ing mounted and located between the planes of movement of saidcarrier-hooks and of the body of said suspension hooks and below thehighest point of said supporting and guiding means to receive saidsuspensionhooks in the plane of their movement as they travel with thecarrier-hooks and when the inclination of these hooks assumes a downwarddirection at the beginning of the descending movement of the chain.

3. In a hog-hoist, the combination of an endless hoisting chaintraveling in one direction and provided with spaced, rigidly attachedprojections, an upwardly inclined rail supported parallel to this chainand extending continuously and in line therewith at the highest partthereof to form a bleeding-rail and a flexible carcass-suspending devicehaving at one end means permitting attachment to it of an animal and atits other end a hook adapted toengage the rail and chain-projectionsbetween the body and the free hooked end of said hook for the purposedescribed and to move along over the same.

'4. In a hog-hoist an endless carrier-chain composed of flat links,means to move it, guide-pulleys on which it is supported in a manner toprovide an inclined, ascending branch, a guide below the inside of thischain-branch, another guide opposite this guide and on the outside ofthis chainbranch which latter moves flatwise between both guides, ableeding-rail extending laterally from approximately the highest pointto which the chain travels and carrier-hooks provided on one of thenarrow edges of the chain so as to travel outside of the guides when thechain moves through between them and to project outside and beyond theouter one of these guides, said carrier-hooks adapted to engageshackling-devices and to elevate them to the bleeding-rail.
